Add space outside the image
Border width is measured in pixels on each side. A 20 px border adds 40 px to the total width and 40 px to the total height. The decoded source stays at its original size; no subject is cropped or enlarged.

Frame the image without moving its edges
Outside padding changes the frame, not the scale of the product. Check the larger pixel dimensions and the remaining transparency before sharing the output.

SYNTHETIC 240×160 ·20 PX EACH SIDE280 × 200 px
240+2×20=280 wide;160+2×20=200 high. The unchanged source begins at 20, 20.
02
Keep transparency inside the photograph
The border is drawn outside the original image rectangle. Transparent source pixels remain transparent inside that rectangle. Export is PNG; original file metadata, animation and encoded bytes are not preserved.
03
Check the frame before publishing
Use the image aspect ratio calculator to compare the new frame proportions. Use the image file size calculator for a separate planning estimate, then inspect the actual downloaded PNG before publishing.
04
Know the browser limits
Use one JPEG, PNG or WebP up to 10 MiB, 4096 px per edge and 8 million decoded pixels. Border width is 0–1000 px; output is capped at 6144 px per edge and 16 million pixels. Only the first decoded still frame is used; browser color handling is not a print-proof guarantee.
05
Keep the source on your device
Decoding, outside padding and PNG creation happen in this browser. No upload endpoint is used. Analytics records fixed interaction categories, not image content, names, dimensions or entered colors.

Questions, answered.
Does adding a border crop or resize my image?
No. This tool places outside padding around the decoded image. The source raster keeps its width and height; the PNG becomes larger by twice the border width in each dimension.
Will transparent pixels stay transparent?
Yes, inside the original image rectangle. The selected solid color is painted only in the outside border. The download is PNG, and original metadata and animation are not preserved.
Are my images uploaded?
No. This tool decodes and creates the output in your browser. Image content, filenames and entered values are excluded from analytics.
